Characterization of the arboreal community from a tropical rainforest fragment (Santa Teresa, Espírito Santo, Brazil), considering the ecological groups of propagules
Abstract
This research project intends to characterize an arboreal community from a tropical rainforest fragment, considering the functional guilds of dispersal, regeneration and stratification. In addition, such analysis will consider temporal (seasonality in fruit) and spatial (topographic gradi-ent) aspects. The main general results obtained here refer to the description of fruiting patterns highly associated to the spatial and temporal heterogeneity of the sampled areas,which apparently is typical from Neotropical rainforests. The topographic gradient studied, if could be generalized to the range of the Neotropical montane rainforest (“Floresta Ombrófila Densa Montana”), points to the importance of the spatial complexity in the maintenance of the functional patterns of these communities, especially those related to the interactions among plant species dispersed by animals and their effective dispersal agents. In the same way, the temporal heterogeneity here observed must be considered as highly important to the maintenance of the diversity of the communities of frugivores. The full understanding of the organization and functioning of tropical communities depend upon more refined analyses of temporal dynamics and spatial heterogeneity, which is reinforced by the results obtained here.
